HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 671,022, dated April 2, 1901.

Application filed December 7, 1899. Serial No. 739,556. (Normoclel.)

To all whom it may concern:

`Be it known that I, WILLIAM JACKSON, a citizen of the United States, residing at Sorrell, in the county of Sullivan and State of Missouri, have invented a new and useful Hay-Stacker, of which the followin gis a speciiication.

My invention relates to improvements in hay-stackers of that class which employ a swinging frame movable in a vertical plane and on a horizon tal axis for elevating and depositing the hay upon the rick or stack.

One object of the invention is to provide improved means for easily adjusting an eX- tensible ricker frame and for locking the parts of said frame in their adjusted positions whereby the frame may be operated for discharging loads of hay upon the stack as it increases in height.

A further object is to provide means for adjusting the pitch or angle of one series of teeth with relation to the other series of teeth in the rake-head of the swinging richer-frame, such adjustment serving to regulate the discharge of the load from the rake-head at different periods in the elevation of the richerframe.

With these ends in view the invention consists in the novel combination and construction of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of my improved hay-stacker,illustrating one embodiment of means between the baseframe and the swinging richer-frame for the purpose of elevating the latter. Fig. 2 is a longitudinal sectional elevation through the hay-stacker shownl by Fig. 1, illustrating the richer-frame in a partly-raised condition. Fig. 3 is a vertical transverse section through the richer-frame in a plane at one side of the rake-head. Fig. 4 is a detail view of the means for operating and locking the adjusting-shaft for the extensible richer-frame.

The same numerals of reference are used to indicate like and corresponding parts in each of the several figures of the drawings.

The base-frame of my hay-stacker is shown by the drawings as consisting of the side rail 10, the cross-rails 11, diagonals orbraces 12, and the stakes 18, all of said rails being secured firmly together,while the stakes are fastened, preferably, at one end of the frame, so as to be driven into the ground for holding the apparatus iirmly in place against the pull or strain of the elevating-rope.

In the embodiment of the invention shown by Figs. 1 and 2 of the drawings I employ a derrick-post 14, having a hinged connection at 14 with the rear cross-head of the baseframe, and this post is provided at its upper free end with a cross-head lo. The derrickpost is held in place by the metallic braceframe 16, which has its lower end suitably attached to the front cross-rail l1, while the upper end of said brace-frame'is confined ou the post 14 by the clamp 17.

The extensible richer-frame 1S is provided or equipped with the pivotal bars 19, the latter being disposed ou opposite sides of the base-frame and connected pivotally thereto as, for example, by the bolts 20. Each pivotal bar 19 is connected with a side rail of the richer-frame by a pair of clips 21 22, one of which clips is fastened to the bar 19, so as to embrace the richer-fram e, whilethe other clip is made fast with the ricker-frame to slidably embrace `the bar 19, whereby the richer-frame is confined in slidable relation to the bars 19, which are pivotally attached to the baseframe. Each slide 21 is provided with an eyebolt 23, and the slides composing the pair 22 are provided With journal-bearings 24, the latter being arranged in alinement with each other transversely across the richer-frame. An adjusting-shaft 25 is journaled loosely in these alined bearings on the clips 22, which are made fast with the pivotal bars 19, so

that the shaft is supported in a stationary position on the pivotal bars, while the Picker- Vframe has slidable relation to said shaft.

This shaft isprovided at its ends with short arms 26, the latter serving as a preferred means for the attachment of the adjustingcables 27 to the shaft. These cables are at the respective sides of the richer-frame, so

locking the shaft in its adjusted position, thus making provision for the adjustment of the richer-frame and for holding said rickerframe in said adjusted positions. As shown by Fig. 4, a ratchet 28 is made fast with the adjusting-shaft, at one end thereof. A feedlever 29 is sleeved or otherwise connected loosely with this adjusting-shaft at a point adjacent to the ratchet, and this lever carries the feed-pawl 30, the latter being pivotally mounted on the lever in a position for engagement with the ratchet. The lever may be operated in one direction for the purpose of making the pawl turn the ratchet, which operatesV to partially turn the shaft 25 in its bearings, so as to coil the cables 27 on said shaft, thereby drawing the bolts 23 and the clips 21 toward the shaft for the purpose of A bracket-plate 31 is secured firmly on one of the clips or slides 22 at a point adjacent to the ratchet, and on this plate is fulcrumed a lever 32. Said lever carries a locking-pawl 33, which is arranged to engage with the ratchet for the purpose 'of locking the same against rotation under the strain or pull of the cables and the richer-frame on the adjusting-shaft, thus maintaining the richer-frame in its adjusted position with relation to the pivoted bars 19. The locking-pawl is disposed below the feedlever and the feed-pawl thereon, so that the locking-pawl will be held against disengagement from the ratchet when the lever 32 occupies the position with relation to the feedlever 29 shown by Fig. 4 of the drawings. The locking-pawl is made fast with its lever, and when the feed-lever and its pawl are raised the lever 32 may be manipulated to withdraw the locking-pawl from the ratchet, and when both of the pawls are free from the ratchet the weight or gravity of the rickerframe or the pull of the elevating-rope thereon or the gravity of the drop-Weight, presently described, may be availed of to slide the ricker-frame toward the pivots of the bars 19, thus shortening the richer-frame.

The rake-head of my hay-stacker is made fast with the outer end of the richer-frame. This rake-head has a series of cross-rails 35 36 and two series of teeth, the teeth of one series being disposed at an angle with the teeth of the other series. The series of teeth indicated at 37 are secured fast to the crossrails 35 36, so that the rails and the teeth are fast with the richer-frame and the teeth substantially in alinement with said richer-frame. The teeth forming the series indicated at 38 .are adjustable by mounting them pivotally at 39 on the fixed teeth 37, so that the pivoted teeth may be disposed in positions at a right angle or at an obtuse angle to the fixed teeth. The pivoted teeth are connected one to the other for simultaneous adjustment through the medium of a connecting-bar 40, which is made fast to the teeth, and in connection with said series of adjustable teeth I employ a locking-rail 41 ,which is hinged or pivotally mounted, as at 42, on the cross-bar 35 of the rakehead. With this locking-rail adjusted to the position shown by full lines in Fig. 2 of the drawings the pivoted rake-teeth rest against the rail, so as to be held thereby in fixed relation and at right angles to the teeth 37, but an adjustment of the locking-rail 41 to the position shown by dotted lines in Fig. 2 permits the connected series of pivoted teeth to incline in a downward and forward direction, as indicated bythe arrow in said Fig. 2, for the purpose of securing an inclined relation to the series of teeth 37 when the richer-frame is elevated to its unloading position. rThis movement of the connected series of pivoted teeth is effected automatically by the weight or gravity of the load sustained by the rakehead, and the locking-rail may thus be adjusted for the purpose of discharging the load vat either of two positions on the elevation of the rake-head with the richer-frame. In the operation of forming the stack or rick itis desirable when the stack is small to discharge the load of hay before the richer-frame and rake-head reach their highest points, and this is eected by moving the locking-rail 41 to the dotted-line position, thus permitting the pivoted teeth to be moved under the weight of the load; but as the stack increases in height the locking-rail is moved to its fullline position in Fig. 2, so as to restrain the connected teeth 38 from movement on their pivots, and thus the load is kept on the rakehead of the richer-frame until the rake-head reaches practically its highest point.

As illustrated in Figs. 1 and 2, I employ an elevating rope or cable and a plurality of sheaves. A pair of sheaves 43 are attached to the rake-head, another pair of sheaves 44 are connected to the cross-head 15 of the derrick-post, and another pair of sheaves 45 is mounted on the front cross-rail 11 of the baseframe. An elevating-rope 46 has its ends fastened to the cross-head 15 of the guide derrick-post, and the strands of this rope are reeved through the sheaves 43, the sheaves 44, and the sheaves 45, both strands of the rope passing through the double sheave (shown by Fig. l) at one side of the base-frame.

To assist in returning the swinging rickerframe to its lowered position, I employ a drop- Weight 47, which is fastened to a rope 4S, the latter being carried through a guide 49 on the post 14 and connected loosely with the adjusting-shaft 25. With the richer-frame in its elevated position after the load shall have been discharged therefrom the strain on the elevating-rope is slaclrened, and the dropweight then acts on the pivoted richer-frame to give an initial impulse thereto, so as to start said frame in a downward direction for returning the parts to their lowered positions, which enables another load of hay to be deposited on the rake-head.

Changes Within the scope of the appended claims may be made in the form and proportion of some of the parts, while their essen- ICO IIO

tial features are retained and the spirit of the invention is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.
